BM3D demo software for image/video restoration and enhancement
Public release v1.7.2 (8 Dec 2009)

------------------------------------------------------------------
Contents
------------------------------------------------------------------
The package comprises these functions
*) BM3D.m : BM3D grayscale-image denoising [1]
*) CBM3D.m : CBM3D RGB-image denoising [2]
*) VBM3D.m : VBM3D grayscale-video denoising [3]
*) CVBM3D.m : CVBM3D RGB-video denoising
*) BM3DSHARP.m : BM3D-SHARP grayscale-image sharepening &
denoising [4]
*) BM3DDEB.m : BM3D-DEB grayscale-image deblurring [5]
For help on how to use these scripts, you can e.g. use "help BM3D"
or "help CBM3D".
Each demo calls MEX-functions that allow to change all possible
parameters used in the algorithm from within the corresponding
M-file.
------------------------------------------------------------------
Installation
------------------------------------------------------------------
Unzip both BM3D.zip (contains codes) and BM3D_images.zip (contains
test images) in a folder that is in the MATLAB path.
------------------------------------------------------------------
Requirements
------------------------------------------------------------------
*) MS Windows (32- or ***-bit CPU) or Linux (32-bit or ***-bit CPU)
note: CVBM3D supports only 32-bit Windows
*) Matlab v.6.5 or later with installed:
-- Image Processing Toolbox (for visualization with "imshow"),
------------------------------------------------------------------
What's new in this release
------------------------------------------------------------------
v1.7.2
+ Fix the ouptut of CVBM3D to be in range [0,255] instead of
in range [0,1]
v1.7.1
+ Fix a bug in VBM3D.m introduced in v1.7 that concerns the
declipping
v1.7
+ Add CVBM3D.m script that performs denoising on RGB-videos with
AWGN
+ Fix VBM3D.m to use declipping in the case when noisy AVI file
is provided
v1.6
+ Make few fixes to the "getTransfMatrix" internal function.
Now, if used with default parameters, BM3D does not require
neither Wavelet, PDE, nor Signal Processing toolbox.
+ Add support for x86_*** Linux
v1.5.1
+ Fix bugs for older versions of Matlab
+ Add support for 32-bit Linux
+ improve the structure of the VBM3D.m script
v1.5
+ Add x86_*** version of the MEX-files that run on ***-bit Matlab
under Windows
+ Add a missing function in BM3DDEB.m
+ Improves some of the comments in the codes
+ Fix a bug in VBM3D when only a input noisy video is provided
v1.4.1
+ Fix a bug in the grayscale-image deblurring codes and make
these codes compatible with Matlab 7 or newer versions.
v1.4
+ Add grayscale-image deblurring
v1.3
+ Add grayscale-image joint sharpening and denoising
v1.2.1
+ Fix the output of the VBM3D to be the final Wiener estimate
rather than the intermedaite basic estimate
+ Fix a problem when the original video is provided as a 3D
matrix
v1.2.
+ Add grayscale-video denoising files
v1.1.3.
+ Add support for Linux x86-compatible platforms
v1.1.2.
+ Fixed bugs related with Matlab v.6.1
v1.1.1.
+ Fixed bugs related with Matlab v.6 (e.g., "isfloat" was not
available and "imshow" did not work with single precision)
+ Improved the usage examples shown by executing "help BM3D"
or "help CBM3D" MATLAB commands
v1.1.
+ Fixed a bug in comparisons of the image sizes, which was
causing problems when executing "CBM3D(1,z,sigma);"
+ Fixed a bug that was causing a crash when the input images are
of type "uint8"
+ Fixed a problem that has caused some versions of imshow to
report an error
+ Fixed few typos in the comments of the functions
+ Made the parameters of the BM3D and the C-BM3D the same
v1.0. Initial version.
